I got this installed on 3.8.1 and it's working fine. I have to say that the installation instructions are pretty vague and have the potential to cause some serious problems if you don't know what you're doing. ie overwriting file folders because the instructions only say to install the files in the "forums folder" to the forums directory. If a person takes that literally and does that they overwrite their forum folders.

I would definitely suggest a more indepth explanation as to how and where to install all of the files in the installation instructions.

No, it doesn't. It overwrites ONLY if there's a file of the same name. The directions are correct.

I love this mod!
Is there plan to include auto updates?
Like giving the option to admin to fetch games straight from v3arcade site and automatically installed them to the forum. Something like overgrab arcade?

Also, I forgot to chmod the required folder to 777 before installing games, not the games is there in my forum just that their images and swf are missing.
How to uninstall these games and reinstall them again?

In your admincp select V3 Arcade then games then find the game and select Delete and press Go.
chmod your folder if you havent and after that just reinstall the games.

Shouldn't be a need to remove the games. Can always chmod the files as well. ;)

It wont install if you dont delete, since it thinks they game allready are installed.
